28 May 2015TL;DR: In this paper, an optical film manufacturing method includes forming a master in which a shape corresponding to a plurality of micro-lens patterns is engraved, forming a low refractive index pattern layer in which the plurality of patterns are formed, by using the master, and imprinting the low-index pattern layer on the high-indexed material layer to form a high-reference pattern on the first surface of a substrate.
Abstract: An optical film manufacturing method includes forming a master in which a shape corresponding to a plurality of micro-lens patterns is engraved, forming a low refractive index pattern layer in which the plurality of micro-lens patterns are formed, by using the master, forming a high refractive index material layer that has a higher refractive index than a refractive index of the low refractive index pattern layer, and imprinting the low refractive index pattern layer on the high refractive index material layer to form a high refractive index pattern layer, on a first surface of a substrate.

TL;DR: An optical article includes an optical element and a low refractive index layer disposed on the optical element as discussed by the authors, which has a haze value of at least 30% and a binder consisting of metal oxide particles dispersed in the binder and a plurality of interconnected voids.
Abstract: An optical article includes an optical element and a low refractive index layer disposed on the optical element. The low refractive index layer having an effective refractive index of 1.3 or less and including a binder, a plurality of metal oxide particles dispersed in the binder and a plurality of interconnected voids. The low refractive index layer has a haze value of at least 30%.
